Bosh opted out of the final two years of his deal with the Miami Heat -- worth $42 million -- and had planned to see what LeBron James decided before making his choice.

But according to ESPN.com, Bosh's conversation with James about his future in Miami this past weekend created enough doubt for Bosh to begin considering his other options, including Houston's offer. The source said Bosh did not know whether or not James was staying in Miami.

Bosh reportedly has been willing to take an annual pay cut by accepting a five-year deal worth $80 million-$90 million from Miami. But ESPN sources say the Heat have been trying to get Bosh to accept a lesser deal.

In the days before free agency began, it was speculated that the Heat's Big Three of James, Dwyane Wade and Bosh would re-sign for less to make more runs at the NBA championship.

Since then, it has been reported that James would not take a discount to return to Miami. He has never been the highest-paid player on his team over his 11-year NBA career.

ESPN.com reported that James' agent, Rich Paul, has sat down with Cleveland Cavaliers owner Dan Gilbert. Paul also has reportedly had discussions and meetings with the Phoenix Suns, Houston Rockets, Dallas Mavericks and Los Angeles Lakers.
